I am starting a project that will be a basic (I stress basic) wolfestein engine. The program will allow the user to walk around a simple building as first person.
I want to model the building my simply defining points and having a line drawn to each defined point, the building only needs to be 2-3 rooms.
Is there software that can create models like this in the mentiond format?
What is the best way to create a model, just draw it out on paper and start writing down all the point?
